FREDERICK M. FUR/BER, OF BEACHMONT, MASSACHUSETTS, AFJSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATEEfiZO'N, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed. October 10, 1921.

This invention relates to machines for performing finishing operations upon boot or shoe parts, and is herein illustrated as embodied in anupper seam-pressing or rubbmg machine of the type described in United States Letters Patent No. 1,570,057, granted Jan. 19, 1926, in the name of the present applicant.

In machines of this type, two important considerations are the rapidity and certainty with which the sides of the seam are separated or opened, and the permanence of the set given the seam as the sides are pressed or flattened down and an objectof the present invention is to improve the operation of seampressing machines in both respects, as hereinafter explained.

In accordance with this object, a feature of the invention is to be found in the provision of a novel moving seam-opening device, as distinguished from the stationary or drag plows ordinarily used. This results in a positive opening of the seam, and eliminates the tendency toward jamming which, espe: cially to inexperienced operators, is diiiicult to avoid with scam-opening devices of the drag type. In the illustrated machine, the novel seam-opening plow member is mounted on the feed hammer, and is given thereby a moventient in an orbital path enabling it most effectively to open successive increments of a seam guided thereto by improved seam-guiding members Thus jamming is impossible, as the opening of successive increments of the scam forms a series of entirely separate operations.

To improve the permanence of the set given the scam, I provide means for heating the work-feeding and pressing hammer, and improve the action of the hammer itself by mounting it relatively to a roller work-sup port so that its sharply-defined front edge crane just at the line of tangency to the surface of the worlcsuppoit. Thus the hammer acts on successive narrow increments of very small area with a relatively heavy pressure, resulting in a. biting as well as a. pounding action on the seam which especially with the aid of heat, imparts a hi gh degree of permanence to the set of the flattened seam. The seam-opening plow is preferably vieldin" mountWi, so as not to interfere with this ing nation.

the base of the machine.

shaft in turn carries a bevel gear meshing Serial No. 506,859.

The invention also contemplates the use of an improved moistening device, and this and other features of the invention, including novel elements and combinations of parts, will be apparent from the following description of an illustrative embodiment of my invention shown in the accompanying drawings, in which Fig. 1 is a longitudinal cros-section of such a machine;

Fig. 2 is a perspective of the operating parts;

Fig. 3 is a sect-ion on the line 33, Fig. 1, showing the operation of the seam guides;

Fig. is a section on the line 1- 1, Fig. 1, showing the mounting of the hammer and Fig. 5 is a view of an alternative form of seam-opener,embodying improved means for moistening the seam.

The machine comprises generally a casing 10, inclosing the operating mechanism, and in which there are formed suitable bearings for a drive shaft 12. This'shaft carries a bevel gear meshing with a bevel gear on a vertical shaft, which is geared to a horizontal shaft in This hor zontal with a bevel gear slidingly keyed to a vertical shaft in the front portion of the machine which in turn carries a bevel gear driving a rotary work-supporting feed wheel 14. The feed wheel 14 and its drive shaft. are carried by a vertically-movable slide arranged to be depressed by a treadle against the resistance of an uplifting spring. A driven shaft 18 is continuously rotated from shaft 12 by a belt indicated by broken lines in Fig. 1. These elements may be, and are illustrated as being, the same as corresponding parts fully described in my above-identified prior application.

A seam is guided into the machine by memhere 20 each having a portion engaging one side of the seam, and another portion mounted in hearings in a plate 22 which can be adjusted vertically by screw 24 and clamped by clamp-nut 26. Arms 28 are carried by the upper portions of members 20, and are connected by a spring 30, tending to twist the lower ends thereof into engagement with the seam. As best shown in Fi 3, an adjust: able stop is provided for mljuetir 5 1e position of iiiidcs 20, i

18. As shown in Fig. 4, the work-engaging. portion to of the hammer is secured thereto by a bolt 48 of such a shape as to make it impossible to mountthe hammer in the machine in reversed position. I

In order to provide the above-described biting action of the hammer on the seam, it

is provided with. a relatively sharp forward edge coming substantially at the line of tangency to the surface or" support 14. Thus thepressii-re is concentrated on a narrow strip immediately adjacent the line of tangency, and is much more effective than i-iv spread over: the usual comparatively large area.

i T he hammer is heated by an electric unit in a stationary member 52, slotted at-its lorward end to embrace the work engaging portion d6.

This hammer-isdriven at a speed ,greater than the peripheral speed work support 14', so that it delivers a wiping or ironing blow on the work, providing a very heavy pressure'on a narrow area which is moved progressively along the'seam. This is found muchmore effective than ironing in such a manner as to distribute the same heavy pressure over a relatively large area. As the work moves more slowly than the hammer, each successive increment of the seam is wiped or ironed down bya plurality of blows seated on a.iorwardly-projecting portion of thehaimner, and guided by a pin 62 passing therethrough and'secured at itsopposit'e ends in the hammer. 1t- 1s yleldmgly urged down ward against its seat on the hammerby a spring 64'. The plow member is given a clawing or scratching motion by the operation of the hammer, so that-it 1s moved periodically into work engaging position and operates to open successive increments of the seam in a novel and'lnghly'eeiiicient manner. During thebiting or seam-compressing action ot edge 50, the'plow 1s free to yield upwardly. I

In operateon the work 18 presentedto the machine, with the seam between guides 20. buccesslve increments of the seam areopened bv ineniberGt) and thereafter flattened by .1 7 e the heated hammer. VYhile successive increments arebt'small areayth'e machine operates at a high I'BiQO'f speed, and the resulting speed oi feeding the workis asxgreat as is desirable. "As is well-linown to those skilled inthe art, it is necessary to withdraw certain kinds of closed seams by depressing worksupport 1% by means oftreadle rod 16. In operatingon some vclasses of work, it is desirable to introducerwater, steam melted wax, starch or a similar fiuid,'between the having a sides of the seam, as this aids in set-ting the seam when pressed, especially ifpressed with a heated member as in the present case, in a manner which is well-known and need not be here discussed. In my prior United States Letters Patent No. 1,295,152, grant-ed Feb. 525', T919, 1 have shown and claimed a "device adapted for introducing such fluids in'a machine having a seamopener of the drag type. In Fig. -5hereinis shown an illustrative form of such apparatus as adapted for the present machine. 1 y

In this improved form, the seam-opening device 60 isprovided-wi'th a passageway to which fluid is delivered, preferably under pressure, 'ifrom' any suitable source, through a rle-Xibletnbe T0. The delivery of the fluid is controlledby a valve including a conical portion 72, normally held against its seat by gravity and by the pressure of theiluid, and a stem portion 7a, which engages the workto open the valve. A set-screw 76isprovided, adjustably to limit the extent to which the valve may open and thereby to control the amount of fluidld'elivered on the work.

While my invention-has been describedas embodied in an illustrative machine of the same generaltype asthose disclosed in my said prior application, itis not my intention to line-t its scope thereby, or otherwisetha-n by the terms of the appended claims. I
